Product Overview

The 100% Brand New GE IC200ALG620-DC acquires temperature and resistance data from field sensors for the VersaMax I/O system. It interfaces with up to four 3-wire or 4-wire RTD sensors (Platinum, Nickel, Copper, Nickel/Iron) and provides 16-bit digital conversion. The module generates its own excitation current, eliminating the need for an external loop power supply.

Engineering Advantages

•  

  Simplified Wiring: The module supplies the excitation current internally. Technicians connect sensors directly without adding external 24VDC power supplies or calculating loop loads, reducing panel complexity and wiring errors.

   

•  

  High Accuracy: 16-bit resolution and automatic self-calibration at power-up maintain ±0.15% accuracy. The module compensates for ambient temperature drift, ensuring reliable data for critical temperature control loops.

   

•  

  Lead Resistance Compensation: Supports 3-wire and 4-wire RTD configurations. The module calculates and subtracts lead wire resistance automatically, delivering accurate readings even with long sensor cable runs.

   

•  

  Comprehensive Diagnostics: The module detects open sensors, short circuits, over/under range, and wiring faults per channel. It reports these statuses to the CPU immediately, enabling rapid troubleshooting.

   

FAQs

•  

  Does this module require an external 24VDC power supply for the sensors?

  No. The IC200ALG620-DC generates the necessary excitation current internally from the backplane power. You do not need to wire a separate 24V supply to the terminal base for the RTD loops.

   

•  

  Can I mix different RTD types on one module?

  Yes. You configure each of the 4 channels independently via the software (Proficy Machine Edition) to match the specific sensor type (e.g., Ch1 = Pt100, Ch2 = Cu10).

   

•  

  What terminal base does it use?

  It mounts on standard VersaMax terminal bases like the IC200TBM002 (Box) or IC200TBS002 (Spring). Use the auxiliary terminal strip on the base to ground cable shields properly.

   

•  

  Is the "-DC" suffix a functional revision?

  Yes. The "-DC" denotes a specific manufacturing revision of the IC200ALG620. It functions as a direct replacement for earlier suffixes (e.g., -AA, -CB) and operates identically in hardware and wiring.
